Abstract

The utility model relates to a special tool for inspecting scales of an acoustic logging instrument in an oil field, which is composed of a body (2), end clamping claws (1), (3) and a middle clamping claw (4). The scale inspection tool has the advantages of simple structure, portability, and flexible operation. The utility model can be used for inspecting scales of the acoustic logging instrument in the course of indoor maintenance and before operation in a well site to ensure the measuring precision of the instrument. Consequently, the utility model can bring convenience and benefits for logging operation.

Description

A kind of acoustic logging instrument scale checking tool
The utility model relates to a kind of special tool that oil field acoustic logging instrument scale is checked that is used for.
Acoustic logging is a kind of logging method of effective measurement formation porosity.The acoustic logging instrument that adopts during acoustic logging comprises sonic log instrument, acoustic amplitude logger and full-wave train variable density log instrument etc.For the certainty of measurement that makes the acoustic measurement instrument keeps stable, need before each well logging construction, inspection apparatus whether meet standard.At present, the method for scale inspection is the propagation time of coming the scale instrument with test pit, aluminium groove (tube) or steel tank different mediums such as (tubes).General test pit or dial drum (groove) volume, weight are big, are difficult for moving, and acoustic logging instrument scale inspection work can only be carried out indoor, also will inject certain amount of fluid (water) in well or in the tube to form the coupling path of sound wave propagation.Thereby this kind scale inspection operation is cumbersome, and scale checking tool, equipment can not move the well logging scene to and go, and is unfavorable for logging operation and increases work efficiency.
Task of the present utility model is to provide a kind of acoustic logging instrument scale, checking tool, and this kind scale, checking tool indoor and production scene can both use easily in the maintenance center, need not the liquid water of annotating during use, also do not need other auxiliary equipment.
The utility model is to realize like this.This instrument is rectangular slide calliper rule shape generally, can adopt aluminium, steel, plastic or other material to make several different appearance and sizes according to dissimilar different spacing acoustic wave apparatus and form series, obtain the different wave train propagation times, satisfy the needs that different velocity of sound instrument calibrations are checked.Its basic structural feature is: this instrument is made up of body (2), end claw (1), (3) and median catch (4).Wherein, end claw (1), (3) are arranged on body (2) two ends, and median catch (4) can be 0-3, is located between the claw of both ends.During use, the end claw (1) of this instrument is placed on the transmitting crystal place of acoustic logging instrument sonic system, median catch (4) and the other end claw (3) are placed on the receiving crystal place of sonic system, between the leather bag of each claw and sonic system, coat thickness state materials such as the butter of some or silicone grease, so that sound wave is listed as by the propagation that normally is coupled of this material, make the acoustic logging instrument operate as normal.
The utility model is simple in structure, easy to carry, use flexibly, utilize it not only when indoor maintenance but also before wellsite applications, all can carry out scale, inspection to acoustic logging instrument, to guarantee the certainty of measurement of instrument, thereby can bring great convenience and benefit to logging operation, be suitable for and apply.
Fig. 1,2,3,4 is a structural representation of the present utility model.Wherein, instrument shown in Figure 1 is used for the emission double reception of scale inspection list or two emission double reception sonic apparatus, instrument shown in Figure 2 is used for the single instrument that receives of scale single transmit, instrument shown in Figure 3 is used for the two emission of scale double reception instrument, and instrument shown in Figure 4 is used for four receptions of scale single transmit and two emission four receives instrument.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
In the utility model, body (2), end claw (1), (3) and median catch each several parts such as (4) be rectangle book plate, and make one, body (2) and each claw are at grade, body thickness is 4-20mm, width is 2-50mm, the claw width is 2-200mm, in the angle that forms between each claw and the body, the obtuse angle is in 100-150 ° of scope, and the distance between each claw is determined according to the position of crystal on the sound, wherein, during structure shown in Figure 1, the distance between end claw (1) and the median catch (4) is 0.8-3.0m, and the distance between end plate claw (3) and the median catch (4) is 0.4-0.8m; Both ends prop up that distance is 0.8-30m between pawl (1), (3) during structure shown in Figure 2; During structure shown in Figure 3, the distance between end claw (1), (3) and two median catch (4) is respectively 0.8-3.0m, and the distance that two middle part cards are is 0.4-0.8m; During structure shown in Figure 4, distance be 0.8-3.0m between end claw (1) and the nearest median catch (4), between all the other each claws apart from being 0.1-0.2m.

Claims (1)

1, a kind of acoustic logging instrument scale checking tool, form by body (2), end claw (1), (3) and median catch (4), it is characterized in that: body (2), end claw (1), (3) and median catch (4) are made one, be separately positioned on body (2) two ends and between the two, this instrument is rectangular slide calliper rule shape generally, each several part is rectangle book plate, and be provided with at grade, the obtuse angle is in 100-150 ° of scope in the angle between each claw and the body, and the distance between each claw is determined according to the position on the acoustic logging instrument sonic system.
